Application filed January 22, I906. Serial No. 297,155.

citizen of the United States, residin at Mil-' waukee, in the county of Milwau ee and 5 State of Wisconsin, have invented certain new and useful Improvements in Dust- Guards for Automobiles and the Like, of v which the followi'ng'is a specification, refer- .ence beinghad to'the accompanying drawings, forming a part thereof.

vent dust and dirt from being drawn over the backsof automobiles andfast-moving ve hicles with the air-currents caused thereby. Itconsists in certain novel features of construction and in the peculiar arrangement and 1 co1nb1nat1ons of parts, as hereinafter partieularly described, and pointed out in the claims.

acters designate the same parts in both figures.

Figure 1"is a rear view of a dust-guard as constructed. and attached to the baekof a vertical cross-section of the same, different positions assumed by the uard when in use eing indicated by dotted ines;

The guard a preferably consists of a light metal frame I) and a covering 0, of leather, waterp'roof canvas, "or similar material. It is attached to the back (I of a vehicle by hinges, one leaf 6 of each hinge being formed with or attached to the lower part of the:

frame b, while the other leaf f is fastened to the top or upper part of the back d. A rod 9 passes through and pivotally connects the h, coiled around the rod g, are atone end attached to or engaged with the fixed hinge members f or other fixed. parts of the device or vehicle, whileat the other end they are attached to or engaged with the guard a, thus serving to hold it normally in an upright position, as shown in the drawings; When the vehicle is moving at-moderate speed, the yielding guard-maintains anapvehicle is running at greater speeds the increased air-pressure thus caused forces the guard backward more. or less, as indicated by dotted lines in Fig. 2, against the tension-of the springs h, and dust or dirt that is raised The main object of this invention is to preout departin 'ed scope of the invention.

In't-he accompanying drawings like 'charvehicle according to the presentinvention, a

eaves or members of both'hinges Springs proximately upright positionybut when the' 4 the vehicle and would otherwise be car ried up behind andintoit is interce ted by the guard and deflected away'from t e occupants of the vehicle. I I

Swinging backward more or less, according to the varying speed of'the vehicle and the varying air-pressure against it, the guard automatically assumes different positions which.

are most effective at different speeds; and under varying conditions for intercepting and deflecting the dust and dirt raised by the passage of the vehicle without checking the speed or obstructingthe progress of the vehiele. Y

I Various changes in details of construction and arrangement of parts may be made withw from the principle and intend- -I cla1m v I 1. A dust-guard yieldingly connected with the back of a vehicle and comprising means adapted tonormally hold it in an upright position and when relieved of wind-pressure to automatically-return it to that posit-ion, substantially as described.

2. A' lust-guard hinged to the back of a vehicle and having a yielding connection therewith tending tohold it in an upright position' and permitting it to be automatieall 'swungbaekward more or less toward a horizontal position; by Wind-pressure, substantially as described.

3. .A dust guard hinged to the back of a vehicle and a spring tending tohold it in an upright position, substantially as described.

4.- A yielding dust-guard hinged at its lower edge to the upper part of the back of a vehicle and a sprin tending to hold the guard in an upright posltion, substantially as described.

5. In combination with a vehicle, a dustguard connected by hinges at its lower edge to the upper part of the vehicle-back, the members of the hinges bein connected by a pivot-rod, and springs eoi ed around. said rod and engaged at one end wltlrfixed parts and at the Tether with saidguard which is yieldingly and normally held thereby an upright position, substantially as described. In witness whereof I hereto aflix my signature in presence oftwo witnesses.
